(01. 112-9) jecting textile fibres on to the edges of plates spaced apart so that the fibres extend around the edges of the plates, across from plate to plate and up into the spacesbetween the plates, means for traversing the fibres along the plates, and means securing the fibres to a backing,

The invention further comprises securing the fibres to the backing by threads laid in the gaps formed in the fibrous mass by the spaced plates.

The invention further comprises securing the fibres to the backing by sewing the two together at the gaps formed in the fibrous mass.

The invention further comprises a machine in which the fibres in sliver form are projected by a roller covered with'card clothing on to thickened edges of the spaced plates.

The invention further comprises a machine in which the fibrous mass carried on and adjacent to the plate edges is traversed along the plates by spikes or teeth (upon an endless conveyor) which project into the mass between the division plates.

The invention further comprises a machine in which the threads which are laid in the gaps in the fibrous mass pass through parts which form the gaps.

The invention further comprises a machine in which the fibrous mass with the threads laid in the gaps, therein is advanced in separate or discrete quantities intermittently after it leaves the division plates so as to leave a gap between the advanced part and the main body of material leaving the plates, and the provision of a sewing machine which crosses the machine in, saidgap and binds the threads to the backing material.

Referring to the accompanying explanatory drawings:

Figure 1 is a sectional side elevation and Figure 2 a cross sectional view on the line 2-4 of Figure 1 illustrating a machine made in one convenient form in accordance with the invention.

Figure 3 is a view of the fibres as they are'passed along the division plates as shown in Figure 2.

Figure 4 is'a view of the right hand portion of Figure l but showing a modification.

Figure 5 is a sectional view of a piece of pile fabric produced in accordance with this invention.

The fleece leaving the dofllng cylinder a of a carding machine or from any other source is delivered into a hopper b from which it is withdrawn bya high speed roller c covered with card clothing d and projected with force on to the lower thickened ends e of spaced division plates 1. There is a casing b around the roller 0. Due to such projection of the fibres on to the division plates, the fibres remain partly outside and extend partly inside between the division plates, and if withdrawn from the latter would present a general appearance similar to what is shown in Figure 3. The gaps at g in the fibrous mass represent the places Occupied by the division plates.

Two endless chains h, one at each side of the machine, carry a cross bar 1 in which are spikes or teeth each spike or tooth being adapted to pass up into the space between two division plates f as the-chains are driven in unison by suitable means. The cross bar i when passing beneath the division plates f rides upon track members a which allow the spikes or teeth to withdraw from between the division plates towards the delivery end of such plates. The action of the spikes or teeth ;i is to enter the bunched and looped fibres projected by the roller c on to the thickened parts eof the plates 1 and carry them forward along the division plates to the delivery end of the latter, when the spikes withdraw and return to take another accumulation of fibres from the inlet to the delivery end of the division plates. More than one cross bar and row of spikes may extend across the chains 71.. a

The thickened part of each division plate is shown as a U strip e attached to the plate. This U strip extends beyond the delivery end of its plate as shown at e in Figure 1 and a thread m is led down each division plate into such U strip at the delivery end and througha hole in the U strip so that the thread lies in the gap as g (Figure 3) in the bunched accumulation of fibres as they pass forward on to a backing canvas or like fabric or sheet n which is moved forward intermittently.

As each bunched and grooved mass of fibres arrives at the end of the delivery plates, it is.

engaged by hooks as 0 which are moved forward mass from the roller After each sewing, the canvas is moved forward a distance corresponding to the spacing of the cross threads from the fibres are proiectedaround the edges of and between the said/plate's and also extend from plate to plate, means for traversing the fibrous mass 'along the plates out of the path of the roller, the plates forming gaps in the fibrous mass, means bringing a backing material beneath the fibrous mass, and means securing the fibrous mass to said backing material.

3. In a machine as claimed in claim 2, means sewing the fibrous mass to the backing material through the gaps in such mass formed by the plates.

sewing machine is shown in Figure 4. The needles of the machine may work through holes 1' in the U strip e so that sewing is completed before the fibrous mass leaves the strips. 7

When the sewing of the material to the backing has been completed, the finished article after cropping resembles a ile fabric having an even close pile t as shown in Figure 5.

It will be seen that my invention provides a rapid and economical method of and means for producing pile fabrics without the necessity for spinning and weaving operations.

What I claim is: 1

1. A machine for producing a pile fabric comprising a plurality of spaced apart plates and means for projecting textile fibres on to the edges 01' the plates so that the fibres extend around the edges of the plates, across from plate to plate, and up into the spaces between the plates, means for traversing the fibres along the plates, and means securing the fibrous mass to a backing.

2. A machine for producing a pile fabric comprising a high speed revolving roller covered with card clothing, means delivering a loose fibrous fleece to said roller, a series of spaced plates in the path of the fleece upon saidroller so that the 4. In a machine as claimed in claim 2, U strips extending over the edges of the plates on to whichthe fibres are projected and along which they are traversed, the said U strips projecting beyond the ends of the plates where the fibrous mass is delivered therefrom and with a hole through the base of each projecting part, sewing means located with their needles each in a U strip so that the needles sew through the holes and the fibrous mass into the backing material.

5. In a machine as claimed in claim 2, an endless conveyor beneath the plates and spikes upon said conveyor projecting into the fibrous material upon such plates in order to traverse it therealong.

6. In a machine as claimed in claim 2, means laying threads in the gaps formed in the fibrous mass by the plates, means advancing the fibrous mass from the delivery ends oi the plates in separate or discrete quantities intermittently so as to leave a gap between the advanced part and the main body of material leaving the plates, and sewing means which cross the machine in said gap and bind the threads through the fibrous material to the backing material.
